Statistical properties of linear prediction analysis underlying the challenge of formant bandwidth estimation

Daryush D. Mehta, Patrick J. Wolfe

A theoretical analysis of the Cram er-Rao bounds on LP estimator variance indicates that the accuracy of bandwidth estimation is approximately twice as low as that of center frequency estimation.  ...  Formant bandwidth estimation is often observed to be more challenging than the estimation of formant center frequencies due to the presence of multiple glottal pulses within a period and short closed-phase  ...  Theoretical lower bounds of frequency and bandwidth estimators Figure 1 (A) illustrates the theoretical approach that investigated the effects of the nonlinear transformation from LP coefficients to formant  ...

Queueing Theoretic Approach to Playout Buffer Model for HTTP Adaptive Streaming

2018 KSII Transactions on Internet and Information Systems  
In this paper, we propose an alternative approach that utilizes the playout buffer occupancy rather than using bandwidth estimates obtained from the application layer.  ...  Without the help of transport layer protocols, it is difficult to achieve accurate bandwidth estimation due to the inherent segment-based transmission of the HAS.  ...  Two rate adaptation schemes have been considered to tackle these issues: a rate shaping approach [7] , and a control-theoretical approach [8] .  ...
